(03-10) 16:05 PDT NORTH RICHMOND -- A man killed in a shooting in North Richmond that injured three others over the weekend had lost one brother in a shooting in the same neighborhood three years ago and another brother in a shooting in Pinole just last month, authorities said Monday.

It is not yet known if any of the three slayings are linked to each other, investigators said.

Nelson Earl Hamilton III, 23, of Richmond and three other victims were shot outside a home on the 1600 block of First Street about 10 p.m. Saturday.

Contra Costa County sheriff's deputies arrived and learned that Hamilton and a woman were taken by ambulance to Doctors Medical Center in San Pablo. Hamilton was then taken by helicopter to John Muir Medical Center in Walnut Creek, where he died.
